DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.

Regarding applicability of 35 U.S.C. §112, ¶16, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.

Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”

Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.

FIG. 1 is a side view of a preferred anti-clog suction tip apparatus 10 in accordance with one or more aspects of the invention. The anti-clog suction tip apparatus 10 is adapted to attach to a hose having a suction source attached thereto, and is useful during surgical procedures for the removal of blood, tissue, and the like, from a surgical site. The anti-clog suction tip apparatus 10 comprises a suction tip assembly 12 and an ejection wire assembly 14.

FIG. 2 is a side view of suction tip assembly 12 shown as part of the anti-clog suction tip apparatus 10 of FIG. 1. FIG. 3 is a back view of the suction tip assembly 12 of FIG. 2. FIG. 4 is an enlarged front view of a portion of the suction tip assembly 12 of FIG. 2.

As seen in FIG. 2-4, the suction tip assembly 12 includes a suction tip 16 having a suction opening 18 at a distal end thereof and a hose attachment portion 20 at a proximal end thereof. The suction tip assembly 12 further includes a handle portion 22 and an ejection wire channel 24. At least a portion of the ejection wire channel 24 abuts the suction tip 16. The ejection wire channel 24 extends from a wire insertion opening 26 located on the handle 22 to a wire exit opening 28 on the suction tip 16 proximate the suction opening 18. In at least one preferred embodiment, the wire insertion opening 26 is a threaded opening. Furthermore, in at least one preferred embodiment, the handle 22 includes a vacuum tunnel opening 29. Covering the vacuum tunnel opening 29 during use of the anti-clog suction tip apparatus 10 increases the vacuum pressure exerted at the suction opening 18.

FIGS. 5A and 5B are side views of the ejection wire assembly 14 shown as part of the anti-clog suction tip assembly 10 of FIG. 1.

FIG. 5A illustrates the ejection wire assembly 14 in a retracted position. FIG. 5B illustrates the ejection wire assembly 14 in an advanced position.

The ejection wire assembly 14 comprises an ejection wire 30, an outer member 32, an inner member 33, an ejection tab 34, and a biasing spring 36. In one or more preferred embodiments, the ejection wire 30 comprises a semi-rigid cable extending from the inner member 33. The ejection wire 30 includes a small ball tip 38 at the end thereof to prevent unintended injury during use.

As seen in FIGS. 5A and 5B, a first end of the inner member 33 is integral with the ejection tab 34 and a second end of the inner member 33 is attached to the ejection wire 30. Furthermore, the outer member 32 encompasses at least a portion the inner member 33 (shown in dotted lines). Finally, the biasing spring 36 encircles a portion of the inner member 33 and is configured to bias the ejection tab 34 away from the outer member 32.

In some alternative embodiments, the ejection tab is formed separately from and is connected to the ejection wire.

As seen best in FIG. 5B, assuming the outer member 32 is immobile, as force is applied to the ejection tab 34, the ejection tab 34, the inner member 33, and the ejection wire 30 advance in the direction of the applied force and the biasing spring 36 contracts. Upon removal of the force, the biasing spring 36 returns to its relaxed position, forcing the ejection tab 34, the inner member 33 and the ejection wire 30 back to the retracted position of FIG. 5A.

Returning now to FIG. 1, the ejection wire assembly 14 is shown threadably attached to the suction tip assembly 12 and in a retraced position. To affix to the ejection wire assembly 14 to the suction tip assembly 12, the ejection wire 30 is first inserted into the wire insertion opening 26 on the handle. Next, the ejection wire 30 is slid forward to occupy the ejection wire channel 24. Preferably, only upon full insertion of the ejection wire 30 into the ejection wire channel 24 can the outer member 32 be threadably secured to the cable insertion opening 26 in the handle 22.

FIG. 6 is a side view of the anti-clog suction tip apparatus 10 of FIG. 1, showing the ejection wire assembly 14 secured to the suction tip assembly 12 in an advanced position. As discussed previously with reference to FIGS. 5A and 5B, the ejection wire assembly 14 is placed in an advanced position by applying force to the ejection tab 34. As force is applied, the ejection wire 30 moves forward.

When the ejection wire 30 is advanced forward, the ball tip 38 passes through the wire exit opening 28 into the suction tip 16 and dislodges any biological debris clogging the suction tip 16, such as blood, tissue, and the like, to unclog the suction tip 16. Such debris may be expelled through the through the suction opening 18. In at least one preferred embodiment, the ball tip 38 does not extend more than three millimeters beyond (protract from) the suction opening 18 when the ejection wire 30 is fully advanced by depression of the ejection tab 34.

To use the anti-clog suction tip apparatus 10 in a surgical environment, sterile packaging in which the anti-clog suction tip apparatus 10 is provided is opened by sterile technique. The anti-clog suction tip apparatus 10 is removed from the packaging and placed on a sterile table to await use by a surgeon or surgical assistant. A hose attached to a suction source is secured to the hose attachment portion 20. Upon activation of the suction source, a vacuum is produced within the suction tip 16, enabling the suction tip 16 to remove biological debris, such as blood, tissue, and the like, from the operation site.

During the course of use, it is believed that the suction tip 16 is likely to become clogged with biological debris. Immediate ejection of the debris is oftentimes necessary in the surgical environment. To remove unwanted debris from the suction tip 16, the user applies force to the ejection tab 34, causing the ejection wire 30 to advance from the ejection wire channel 24, through the wire exit opening 28, and expel the debris clogged in the suction tip 16 through the suction opening 18. Some debris that is dislodges then may also be suctioned. To retract the ejection wire 30, the user removes the applied force from the ejection tab 34. The biasing spring 36 causes the ejection tab 34 to return to its initial position, thus retracting the ejection wire 30. When retracted, the ejection wire 30, and in particular the ball tip 38, is retained within the wire channel 24 and does not obstruct normal suctioning of the debris during use of the apparatus 10.

An added advantage of an anti-clog suction tip apparatus 10 in accordance with one or more embodiments of the present invention is the location of the ejection wire assembly 14. More particularly, the ejection tab 34 is located on the handle 22 and not in the user's line of sight and thus does not obstruct the user's view during a surgical procedure.

In one or more preferred embodiments, the anti-clog suction tip apparatus 10 is intended to be disposed after a single surgical use. After use, the anti-clog suction tip apparatus 10 will include biological and potentially hazardous debris, and thus, should be disposed according to any applicable HAZMAT protocol.

In at least one preferred embodiment, a secondary wire is supplied to be inserted into the suction tip 16 through the suction opening 18 to more completely clear debris if the ejection wire 30 is unable to completely expel the debris. It is further contemplated that alternative ejection wires may be included that have other sizes, dimensions, and profiles of ball tips, and that have wires of different diameters and different rigidity characteristics.

FIGS. 7 a-7 d and 8 a-8 b show additional views of another preferred anti-clog suction tip apparatus 110 in accordance with one or more aspects of the invention, which apparatus 110 is similar in appearance to apparatus 10. The anti-clog suction tip apparatus 110 comprises a suction tip assembly 112 and an ejection wire assembly 114.

Based on the foregoing description, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those specifically described herein, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing descriptions thereof, without departing from the substance or scope of the present invention.

Accordingly, while the present invention has been described herein in detail in relation to one or more preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for the purpose of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended to be construed to limit the present invention or otherwise exclude any such other embodiments, adaptations, variations, modifications or equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.
